Intermolecular Interactions
Covalent bonds in molecules are strong. The breaking and making of covalent bonds involves large amounts of energy (e.g. chemical explosives). In addition to strong chemical bonds that define the connectivity between atoms with

As a chemistry student you will be required to write laboratory reports for some or all of the experiments you perform. The reader of a well written lab report should understand why t

3. What we teach : Photoelectric effect (Lecture 3)
You may have encountered the photoelectric effect previously. Now you know about retarding potentials and how the experiment is actually done! You were asked to move between graphical representations of

Dr. Jill Robinson
Key Idea about Nanoscale: Characteristic properties of matter do change with size, especially in the nano and atomic size scales. How will you determine the size of these particles?

Qualitative Analysis: The Nine-Bottle Problem
Introduction In this experiment you will be given nine numbered bottles, each of which contains a different unknown solution. Your task will be to identify the contents of each bottle, using no other rea

Molecular orbital theory
Reconsider H2 The wavefunctions add and subtract to result in the wavefunction experienced by the molecule. This is the basis of the covalent bond The electrons occupy the same orbital and have opposite spins. This new orbital tha

Polyelectronic atoms

If you try to specify/measure the exact position of a particle you cannot simultaneously know its momentum exactly. If you try to specify/measure the exact momentum of a particle, you c

Planck's quantum theory
Let's look at how the color of a filament changes as the temperature changes. As the resistive wire (filament) heats up it goes from red to white hot. Color is related to temperature!

Radioactivity
1896 Henri Becquerel discovers that a Uranium ore emitted "rays" that exposed a photographic plate (in the absence of sunlight). The original ore after emission of the rays has a component that has a different chemical properties (is a diffe

Bond strength and bond length
As the number of bonds between two atoms increases, the bond grows shorter and stronger Carbon is remarkable in its ability to catenate, that is bond to itself so as to form long chains. Ofcourse life as we know it depends on
